imageInstructions For Using RxP When Taking An Emissions Test

NOTE :The engine "absolutely" must be getting enough fuel and air for RxP to work properly.

Before you add RxP to your gasoline, check for apparent vehicle defects. If the vehicle has mechanical problems they should be repaired according to manufacturer recommended specifications before taking an emissions test.

1. Fill the gas tank and add one ounce of RxP per ten gallons of gasoline. Be sure you treat the gasoline that is already in the tank.

2. Drive the vehicle allowing enough time for the engine to be de-carbonized (most vehicles can be tested 30 minutes after adding RxP, but for best results run a full tank through the vehicle). If the vehicle is inspected for emissions before the de-carbonization process is completed, the emissions may go up. Do not be alarmed. The de-carbonization takes time, especially on engines that have excessive build-up.

3. Fill gasoline tank and add one ounce of RxP to ten gallons of gasoline.

4. Change oil, oil filter and air filters. RxP will not work if the engine is not getting enough fuel or air (oxygen).

5. The engine is now ready to be tested, however we suggest that before taking an emissions test you turn off the air conditioner and run the vehicle long enough to insure engine is raised to normal operating temperature.

Note: RxP is less effective in air cooled engines that are not equipped with an EGR system. The emissions should still be reduced significantly, however because of the design of some of these engines the emissions levels may not drop to a level low enough to pass some emissions tests.

In an informal survey conducted by RxPProducts, we learned that 98% of the vehicles using RxP passed federally mandated emissions tests on the first attempt. The 2% that failed did so because:

1) they failed to read and follow the instructions,
2) the vehicle had severe mechanical problems (such as a faulty exhaust system, cracked head or manifold, defective carburetor or other apparent serious malfunctions), and
3) the engine was not getting enough fuel or air.
